Summary Statistics for a Quantitative Data In this activity you will collect your own data and answer questions about your data set.

1. Ask 16 friends or relatives who live on Long Island to use a map app on their phone and determine the distance, in miles, that they are located from the Ammerman Campus of Suffolk Community College. Only collect information from one person per household. Round the distance to one decimal place and record the values below.

1. Determine the sample mean, median, mode, range, variance and standard deviation of the data set. Round all final answers to two decimal places.

Mean: Median: Mode:

Range: Variance: Standard Deviation:

1. Based on your data set, would a distance of 12 miles be considered an outlier? Determine the upper fence and lower fence and explain why it is or is not an outlier.

Measures of Center and Histograms

For each histogram, describe the shape of the distribution and estimate the values for the mean and the median by looking at the graph (no calculations are necessary). Then determine which would be a better measure of center for the data set.
